The present invention relates to bumpers for automobiles and the like; andian object thereof is to provide a device of that character having improved cushioning parts for the impacts thereon; another object is to provide such a device having improved parts for mounting the same on an automobile; another object is to provide such a device which shall be very simple and economical in construction and eificient in operation.

These and any other and more specific ob-' jects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure particularly described in the body of this specification and illustrated by the accompanying drawings, in which: y

Figure 1 is a top plan view of an automobile bumper and of the forward end of an automobile on which it is mounted;

'Figure 2 is a top plan view of portions thereof showing a modified construction of the mounting means;

Figure 3 is a top plan view of an end portion of the bumper;

Figure 4 is an elevational rear view of said end portion, partially sectioned vertically on line l4 of Figure 3; Y a

Figure 5 is a horizontal sectional view thereof taken on line 55 of Figure 4; v

Figure 6 is a vertical sectional view of the same taken on line 6-6 of Figure 3; and

Figure 7 is a rear side viewof the end portion of a blank or metal strip from which the bumper is made. y

The bumper designated generally 1, shown in these drawings mounted on an automobile 2, comprises a resilient horizontal impact bar 3 whose end portions 4 are divided into parts or tongues 5, 6 as by horizontal slits 7 extending from the ends of the metal strip or .blank 8 from which the bar 3 is formed, as shown in Figure 7 These end portions 4 are curled rearwardly and inwardly, and the tongues 5 thereof are then curled forwardly and outwardly so that their bevelled extreml ities 9 extend parallelly and in contact with the rear surface 10 of the middle portion 11 of the impact bar, the other tongue 6 extending inwardly and in approximately parallel 1931; serial nogseanag f ing parts and carried by brackets T 14011 the frame 15 of the automobile (as shown in Figtending forwardly rearwardly as shown in the views i a by details of construction ofthe particular AUToMoBILnBUMrEn I w i passing through openings 13 in these mounture' 2) or passing through the horizontal sup: porting rear bar 16 secured at 17 onrsaid frame as: seen in Figure 1) I When the front of the bar3 receives an im- E pact its inner surface contacting the bevelled yends9 of the bars resilient tongues 5 flexes these tongues thus cushioning the impact at this contacting point, said'bevelled end ,9

The said space is shown filled by a resilient member or rubber plug 24, held in place as by a pin 25, to deaden the sound caused by the frictional engagement of the end 9 with the bars surfacelO, and also to cushion impacts 7 on the bar." 7

The invention beingintended to be pointed out in the claims, is not to be limited'to or embodiment thereof illustrated by the drawings or hereinbefore described.

, I claim:

' 1. In an automobile bumper: a bar having rearwardly extending end portions curved in a horizontal plane, comprising tongues continuously curved toward the bar,vand mount ing tongues extending approximately parallel with the bar intermediate its end portions. 2. In an automobile bumper: a bar having rearwardly extending end portions curved in a horizontal plane, comprlslng tongues continuously curved to bearing relation with the bar, and mounting tongues extending apme proximately parallel with the bar intermediate its end portions. r 3. In an automobile bumper: a bar having rearwardly extending end portions ellipti- 5 cally curved in a horizontal plane, comprisingtongues continuously curved toward the bar, and -mou nting tongues extending ap proximately parallel with the bar intermediate its wendportionsr 10 4.
